;;; Commentary:

;; Coq is a proof assistant (http://coq.inria.fr/).  This code run an
;; inferior Coq process and defines functions to send bits of code
;; from other buffers to the inferior process.  This is a
;; customisation of comint-mode (see comint.el).  For a more complex
;; and full featured Coq interface under Emacs look at Proof General
;; (http://zermelo.dcs.ed.ac.uk/~proofgen/).
;;
;; Written by Marco Maggesi <maggesi@math.unifi.it> with code heavly
;; borrowed from emacs cmuscheme.el
;;
;; Please send me bug reports, bug fixes, and extensions, so that I can
;; merge them into the master source.

;;; Installation:

;; You need to have gallina.el already installed (it comes with the
;; standard Coq distribution) in order to use this code.  Put this
;; file somewhere in you load-path and add the following lines in your
;; "~/.emacs":
;;
;;   (setq auto-mode-alist (cons '("\\.v$" . coq-mode) auto-mode-alist))
;;   (autoload 'coq-mode "gallina" "Major mode for editing Coq vernacular." t)
;;   (autoload 'run-coq "inferior-coq" "Run an inferior Coq process." t)
;;   (autoload 'run-coq-other-window "inferior-coq"
;;     "Run an inferior Coq process in a new window." t)
;;   (autoload 'run-coq-other-frame "inferior-coq"
;;     "Run an inferior Coq process in a new frame." t)

;;; Usage:

;; Call `M-x "run-coq'.
;;
;; Functions and key bindings (Learn more keys with `C-c C-h' or `C-h m'):
;;   C-return ('M-x coq-send-line)     send the current line.
;;   C-c C-r  (`M-x coq-send-region')  send the current region.
;;   C-c C-a  (`M-x coq-send-abort')   send the command "Abort".
;;   C-c C-t  (`M-x coq-send-restart') send the command "Restart".
;;   C-c C-s  (`M-x coq-send-show')    send the command "Show".
;;   C-c C-u  (`M-x coq-send-undo')    send the command "Undo".
;;   C-c C-v  (`M-x coq-check-region') run command "Check" on region.
;;   C-c .    (`M-x coq-come-here')    Restart and send until current point.

;;; Change Log:

;; From -0.0 to 1.0 brought into existence.

Major mode for interacting with an inferior Coq process.

The following commands are available:
\\{inferior-coq-mode-map}

A Coq process can be fired up with M-x run-coq.

Customisation: Entry to this mode runs the hooks on comint-mode-hook
and inferior-coq-mode-hook (in that order).

You can send text to the inferior Coq process from other buffers
containing Coq source.

Functions and key bindings (Learn more keys with `C-c C-h'):
  C-return ('M-x coq-send-line)     send the current line.
  C-c C-r  (`M-x coq-send-region')  send the current region.
